DRAFTfRIGGNG-SUPPORTING ARRANGEMENT.

Application ledAngnst 4, 1924. lSerial No. 729,921.

This invention relates to drait rigging supporting means and more particularly to retaining means tor self-centering devices.

rlhe use ot a selt-centering device broadly is old. Herctoiore such devices have been mounted v.on carry irons in a manner tending to prevent displacement of the self-centering device with respect to the carry iron.

For the most part such arrangements are generally successtul7 except when a car is turned over, whereupon the selt-centering device has been-tree todrop away from the carry iron and -be lost.

One object ot the invention is to provide simple, reliable and durable means for retaining a self-centering device in its proper association with the `carry iron under both normal and abnormal circumstances.

Anotherobject is to provide an arrangement in which selective retaining means may be used for preventing displacement of a self-centering device.

Another object is to provide a simple and efficient combination otcarry iron7 self-cen tering device and retaining means adapted to meet all vot the requirements under conditions which are encountered in service.

These and other objects are vaccomplished by means ot the arrangement disclosed by the accompanying` sheet ot' drawings in which Figure 1 is a irontelevation oit-a striking block or casting having a carry iron integrally formed therewith, a sel't-centeringdevice and retaining means tor said seltfcenvtering device to prevent displacement otthe latter.

Figure 2 is a sectional view taken in the plane ot 'line 2-2 ot Figures 1 and 3, and showing a vertical bolt for retaining the self-centering device against displacement.

Figure 3 is a sectional view taken in the plane of lines 3 3 of Figure 2.

Figure et is a detailed sectional view taken in the plane of line 4-Ll ot Figure 3 and showing the elongated ears or projections torming the head of the vertical retaining` bolt.

Figure 5 is a sectional view taken in the plane of line 5-5 of Figure 6 and somewhat similar to that shown in Figure 2 but show ing a horizontally arranged retaining bolt instead of a vertically arranged retaining bolt, and

. relianceshouldnot be .placed upon the .tofprevent displacement ot the cai Figure 6 is a sectional view taken in the plane ot lineG-G oit Figure 5.

rl-he various novel features-ot the in\fen tion will be apparent trom the vfollowing description and drawing and will be particularly pointed out in the appended claims.

Referring to the figures ot the draw igs, it will be noted that the invention is illustrated lin connection with a striking rcasting `10 having integrally formed therewith a cai` ry iron 11. A self-centering device including a carriage 12 is mounted upon roller-s sitionwith respect to the carry iron ll. Idue to the tact that the carriage 12 is mounted down -in between the transverse side walls: 16 of the carry iron 11. However, entire lapping Vopt-the carriage and side t* ofthe carry iron 11 under all circumstar e ge 12 with respect tothe carryiron, for it apparent that under some circumstances Ytor example, when a railroad car is tipped e r, it would be possible for the carriage or-seltcentering device 12 to be entirely disengaged from the carry iron 11 and lost. rlhis will be particularly true when it is realized that the degree ot overlap between the carriage 12 and the side walls 16 is not as great as the clearance between the top interior wall 17 ot the striking casting 10 and the top wall 18 ot the coupler shank 19, which is mounted upon and supported by the carriage 12 This condition necessarily must exist to facilitate the assembly of the coupler and self-centering device within the striking casting 10, particularly where the carry iron 11 is formedintegrally with the striking casting.

To retain the selt-centering device within the striking casting under both normal and abnormal conditions, l have provided a selective retaining arrangement. ln this connection, it will be noted that the self-centen ing device or carriage 12 is provided With a longitudinally extending opening 2O throughout its length and through which a longitudinal bolt 21 may pass, as shown particularly in Figures 5 and 6 and in dot and dash lines in Figure 1. This horizontally arranged retaining bolt not only cooperates With the seit-centering device 12 but also with the side Walls 22 of the strilring casting, it being noted that the longitudinally arranged retaining bolt 21 passes through openings 23 in the side Walls iilormally the horizontally arranged retaining bolt 21 is out oit supporting relationship with respect to the self-centering device, that is to say, the horizontally extending retaining bolt 21 does not engage any part oit the self-centering device and on the other hand extends through the opening therein and has a relatively large clearance with respect thereto to permit a free horizontal swinging movement ot the seit-centering device 12 and the attendant vertical movement occasioned by the riding oi said seltcentering device on the rollers 13.

The seit-centering device may be retained against displacement by the use of a vertical retaining bolt as distinguished from the horizontal retaining bolt. To accomplish this result a vertical retaining bolt 24; is passed through vertical alignment openings 25 and 26 in the carry iron 11 and carriage 12. The opening 25 in the carry ironv is elongated and defined by the side Walls 27 to permit tree horizontal movement oli' the carriage or self-centering device 12. The opening 26 in the carriage 12 is elongated transversely with respect to the elongation of opening 25 to permit an upwardly vertical insertion or the vertical retaining bolt 2e and more particularly to permit free vertical movement of the projections 28 torming the head ot the vertical retaining bolt. titte-r the vertical retaining bolt 2e is thus raised through the o aenings 25 and 26 until the head is lifted above the horizontal surface 29 Within opening 20, the bolt 24 may be rotated through an angle ot 90 degrees on its vertical aXis to permit the head projection 28 to drop down into pockets 30 formed in the carriage 12 to prevent accidental upward movement ot the bolt 2li. Upward movement ot the bolt 24 normally is prevented by a key 31 Which is passed through the bolt alter the latter is set in position.

By means of this arrangement the carriage or self-centering device is selectively retained against displacement under both normal and abnormal conditions.

lt is my intention to cover all modifications ot this invention 'falling Within the spirit and scope ot the following claims.

l claim:

1. In draft rigging supporting means, a striking block having a carry iron, a seltcentering device supported thereby having different portions extending in dii'l'erent directions engageable by retaining means, means extending in one direction engageable w'th one of saidportions tor retaining said self-centering device against displacenient, anothe" portion of said device being engageable with other retaining means er1 tending in .1 diiierent direction.

2. ln draft rigging supporting means, a striking block having a carry iron, a seltcentering device having a plurality,T oi openings extending in diil'erent directions, and means passing through one Ot said openings for retaining said seit-centering device against displacement, the other opening beingadapted to receive a ditlerent retaining means.

3. ln dra'lt rigging supporting means, a striking block having a carry iron, a seltcentering device supported thereby and havine' a horizontally extending opening and a vertically extending' opening, said openings being selectively used for the reception ol a retaining member to prevent displacement of said selfecentering device.
